Suspension, gearing set up for Turbo ZX14
I'm looking for some suggestions in regards to tweeking the suspension and gearing for drag racing my Turbo bike. I run the quarter mile. The bike is making 250HP 170ft.lbs on stage1 and 350HP 210ft.lbs on stage2. I weigh 250lbs suited.I'm currently running a 16T front and 41T rear sprocket. My best time is 8.75@ 172mph. My 60ft was 1.62. I looked at my under tail and the bike is bottoming out bad. The bike pulls the front end when strapped down even in 4th gear at the 1/8th mile. It's almost an unpleasant experience. I'm lowered and my arm is 8" over. I run an air shifter and hit the button for higher boost when shifting from 1st to 2nd. Help!!!!!!!

You need a drag shock set up for you weight , wheel base and power ... Gearing ? well what works for one guy doesn't work for the next guy .. You will just have to try gears till you find something that fits you riding style ..

Most of the dyno sheets read 135 to 140 tq for a 250 hp set up,,, I thought , ????? 170 is a big # Any one Else making this tq with 250 hp ?
How ? Must copy

Just checked the dyno sheet for my old 12 ...
288hp 148tq @ 6 psi and 363hp 192tq @ 14psi and that was a pretty trick set-up running a water cooled charge cooler so 170 lbs tq @ 250hp is some serious number.

I did some checking and I'm going to put a Busa rear spring in place of the stock spring I currently have. Also went back to a 17T front paired with my 41T rear instead of a 16T front. Going to test Friday. I expect similar 60ft times with a more controlled ride. Hope to see 8.60's at 175mph. Will post results next week.

18/45 or even 19/48. Keeps the chain off the swingarm. With the Turbo power its better not winding the chain tight around a small counter sprocket. I run 18/45 for the track and 19/45 on the street

On My turbo Busa I ran my best 1/4 mile times with 18/38. You got a lot of torque and it should pull a tall gear.

The Busa spring mod worked like a champ this weekend. I tried 17/41 and couldn't get the bike to 60ft very well Best pass was 8.95 @ 170 on Friday 1.74 60ft. Went to 16/42 for Saturdays event and ran a 8.73 @171mph 1.60 60ft. The pass was smooth and the bike was very controllable. Also won the Top Dawg Trophy for fastest pass out of 190 vehicles. Sunday the bike went 8.70 @174mphno changes made from Sat to Sunday. I'm gonna run with this setup for awhile to see if I can't get 8.50's out of it with some practice.
